Efficacy of Different Final Irrigant Activation Protocols on the Penetration Depth of a Calcium Silicate-Based Bioceramic Root Canal Sealer

Introduction: The purpose of the research was to assess the impact of the final irrigant activation of ER: YAG laser with PIPS technique and ultrasonic irrigant activation by Ultra-X endoactivator (Changzhou Sifary Medical Technology, China) on the penetration depth of the bio-ceramic sealer (Meta Biomed Ceraseal, Korea).Methods: 60 human mandibular premolars were utilized in the investigation. The access cavities were made. To achieve a size #40 apical preparation, all teeth were instrumented using a crown-down technique, using a set of ProTaper Next rotary instruments. Following biomechanical preparation, teeth were divided equally into 4 groups (n=15) G1 (Manual dynamic agitation), G2 (Passive ultrasonic instrumentation), G3 (PIPS technique), and G4 (No activation). The sealer was combined with the Rhodamine B dye to analyze the penetration of the sealer through the CLSM. Obturation was performed out in a single cone approach. Three slices (2 mm) were cut off from each root to symbolize the coronal, middle and apical thirds. The finding was tabulated and subjected to statistical analysis.Results: There was substantial variation among different groups. The PIPS group had the greatest value, followed by PUI, then MDA, while the lowest value was found in No activation group.Conclusion: The final irrigant activation strategy had a considerable impact on sealer penetration into the dentinal tubule. Use of PIPS tip or PUI seems advantageous in dentinal tubule penetration of a calcium silicate bioceramic sealer
